Title: Press-on closure with peelable end panel
Inventor: ROTH DONALD J
IPC: B65D17/50
Filed: 1992-12-23
Granted: 2004-02-24
Abstract: A press-on closure (10) for a tubular container (12). The closure includes a molded plastic frame (14) having a ledge (28) on which an end panel (16) is seated and to which the end panel is peelably secured. The end panel has a free outer peripheral edge unbonded to the frame. The resultant closed container is subject to retorting with the result that heretofore the end panel could axially outwardly deform and possibly initiate internal peeling. To prevent this peeling, the frame is provided with a thin flexible integral flange (36) forming a continuation of the ledge on which the end panel is seated. The end panel is also peelably bonded to the flange and the flange deforms or deflects with the end panel. The frame has a press fit onto the container, which is preferably in the form of a metal can, which at the end thereof to be closed by the closure is provided with a radially outwardly directed curl (48). The curl terminates in a raw edge (54) and is so shaped that when it is seated within a groove in the underside of the frame, the raw edge is embedded in a skirt portion of the frame to permanently and sealingly lock the curl within the frame.

Abstract: A process for selectively forming an antislip surface on a product thermoformed from a plastic sheet is applied to truck bed liners, for example. The surface of the plastic sheet of HDPE or other thermoplastic material is cleaned and masked, to prepare a good molecular bonding surface on selected surface areas. A sprayable or liquid polymer selected to achieve desired charac teristics of hardness and toughness without brittleness, such as a thermosetting elastomeric polymer, is formed into droplets, which are sprayed or otherwise applied onto the selected surface area. The droplets form a stippled pattern of primarily separate bumps across the selected surface area to be treated, occupying substantially less than 50% of the exposed area. After partial hardening of the bumps, the plastic sheet is thermoformed at thermoforming temperatures to produce the thermoformed product.      Thermoforming tightly bonds the bumps or droplets to the thermoplastic sheets material, hardens the droplets forming macroscopic asperities, increases or enhances the three dimensional surface relief, and explodes some droplets with entrapped air to increase surface roughness.

Title: Low frequency audio conversion circuit
Inventor: ODA MIKIO
IPC: H04N5/60
Filed: 1996-02-27
Granted: 2000-08-29
Abstract: A low frequency audio conversion circuit for converting the frequency of low frequency audio components. An input audio signal includes a low frequency audio component lower than the frequency a speaker can reproduce. The low frequency audio component is filtered and extracted by a low pass filterand full-wave rectified to generate even-numbered harmonics of the low frequencyaudio component. Secondary harmonics are extracted from the even-numbered harmonics and added to the input audio signal after being amplified to an appropriate level. When a speaker whose low frequency sound reproduction characteristics are poor is used, and a low frequency component lower than the frequency the speaker can reproduce is supplied, the low frequency audio component is reproduced as secondary harmonics which fall within the frequency range of the speaker. Thus, the low frequency audio component is compensated, and a powerful sound is reproduced at a low cost without degrading the sound.

Title: Intelligent call forwarding
Inventor: RAO USHA
IPC: H04Q3/00
Filed: 1996-04-01
Granted: 1999-09-28
Abstract: Intelligent call forwarding is implemented through an intelligent network. The intelligent network includes a Service Switching Point (SSP), a Service Control Point (SCP), and a Service Management System (SMS). A call to a network subscriber is routed to the SSP which is used to detect Call Forwarding "triggers" -  conditions which require the SSP to initiate selective Call Forwarding service. When a Call Forwarding trigger is detected the SSP passes the calling party's number to the SCP and requests call handling instructions from the SCP. The SCP provides the call handling instructions, as provisioned by the subscriber, to the SSP, and the SSP then forwards the call in accordance with the instructions. The SMS formulates and sends commands to the SCP for such purposes as changing the stored subscriber instructions or updating service features. By provisioning the SCP with appropriate instructions the forwarding destination for a call may be made to depend upon the time of day, day of the week, caller's identity, and/or status of the called telephone.

Abstract: A rare earth element-doped multiple-core optical fiber has an outer cladding layer and a plurality of cores each covered with a primary cladding layer. The cores are positioned substantially on a central axis of the outer cladding layer and separated with a predetermined spacing S from each other by the primary cladding layer. The outer cladding layer is made of SiO2, or SiO2 to which a dopant like F, Ge, etc. is added. The primary cladding layer is made of SiO2 doped with Er, or SiO2 doped with Er and F together and formed to have a predetermined thickness of 1.0µm - 1.5µm to form the predetermined spacing S. The soot glass rods for cores and primary cladding layers are immersed in an Er-compound solution, then picked up, dried and consolidated to form Er-Al co-doped SiO2 - GeO2 transparent glass rods. The glass rods are inserted into a quartz tube and collapsed by heat to fabricate an optical fiber preform rod, then heated to be drawn to provide an Er-doped multiple-core optical fiber.

Abstract: A method and apparatus for use in locating a vehicle driver, passenger or object in the vehicle for controlling vehicle systems including the positioning of vehicle sideview mirrors in relation to the driver's eyes to maximize the view of traffic on either side of the vehicle or the characteristics of vehicle airbag deployment. The location of a driver's or passenger's eyes or the location of an infant's seat is derived from the adjustment by the driver (or passenger, if capable of doing so) of adjustable light beam(s) emanating from light source(s) or illuminated indicia, until it (or they) intersect the driver's or passenger's eyes or illuminate a target, e.g. a child or an infant's seat, in the front passenger's seat. From the angles of adjustment of the light beam(s) and other known coordinates of the vehicle, the location of the driver's or passenger's eyes or the target may be computationally derived as a set of Cartesian coordinates. The determined eye location of the driver may be used together with the known mounting locations of the driver's and passenger's sideview mirror assemblies to derive exterior sideview mirror pitch and azimuth adjustment signal sets correlated to the vehicle blind spots. The adjustment signals are applied to servo motors operating in a feedback control loop to correct the actual driver's side and passenger's side sideview mirror pitch and azimuth settings to properly reflect images of the driver's side and passenger's side vehicle blind spots to the driver's eyes. The determined eye locations of the driver and passenger or the target location of the infant's seat may be also or alternative employed in the control of the airbag deployment system and in other vehicle safety and comfort systems.  The relative fore-aft distance away from the airbag and the height of the person or target can be computed, and airbag deployment force and/or duration adjusted to compensate for deviation from the standard height and fore-aft distance.
